AI Technical Summary

Benefits of technology

The present patent is about a new strawberry variety called "Yakima" and methods for breeding and producing hybrid strawberry plants with resistance to Fusarium oxysporum. The "Yakima" variety was deposited as a cultivar in the National Center for Genetic Resources in 2012. The patent describes methods for crossing strawberry plants to create progeny plants, growing them, and selecting resistant plants using molecular markers. The "Yakima" variety can also be used to create hybrid strawberry plants by crossing with other strawberry plants. The technical effect of this patent is the creation of a new strawberry variety with resistance to Fusarium oxysporum, which can help protect against a disease that affects strawberries.

Problems solved by technology

Despite having the world's highest average yield / hectare, production in the United States over this time period did not show the sharp increases in production obtained in some other countries, including China.
Fusarium wilt is present in all major strawberry production areas in California, and constitutes a significant threat to this $2.6 billion industry, which produces over 80% of the fresh strawberry fruit consumed in the United States.

example 1

of ‘Yakima’ (a.k.a. ‘109733’)

[0104]‘Yakima’ (a.k.a. ‘109733’) is the result of a controlled-cross between a female parent cultivar designated (Aida′, a.k.a. ‘106734’,) an unpatented, proprietary strawberry plant variety made by the inventor and a male parent cultivar designated ‘Lili’ (a.k.a. ‘101983’ or ‘Lily’, U.S. Plant Patent No. PP25,849) and was first fruited in Watsonville, Calif. growing fields. Following selection and during testing, the plant was originally designated ‘109733’ and subsequently named ‘Yakima’.

[0105]The new variety was asexually reproduced via runners (stolons) by the inventor at Watsonville, Calif. Asexual propagules from the original source have been tested in Watsonville growing fields and to a limited extent, grower fields in high elevation. The properties of this variety were found to be transmissible by such asexual reproduction. This cultivar is stable and reproduces true to type in successive generations of asexual reproduction.

ical and Phenotypic Characteristics of ‘Yakima’

[0106]The following traits and photographs in combination distinguish the strawberry variety ‘Yakima’ from known strawberry varieties. In addition, the new cultivar was confirmed to be a unique strawberry germplasm when tested against the California Seed & Plant Lab, Inc. (Elverta, Calif.) database using Short Sequence Repeats (SSRs). Plants for the botanical measurements in the present application were grown as annuals. Any color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The botanical measurements listed in Table 1 were made and recorded during the month of June.

[0107]‘Yakima’ is distinguished from its maternal parent ‘Aida’ by the shape of its fruit. The fruit of ‘Yakima’ is mostly conical, different from the longer somewhat flat wedge shape of the fruit of its parent ‘Aida’. ‘Yakima’ is similar to the strawberry plant nam...

ting of ‘Yakima’

[0112]The ‘Yakima’ cultivar is primarily adapted to the climate and growing conditions of the central coast of California. This region provides the necessary temperatures required for it to produce a strong vigorous plant and to remain in fruit production from March through October. The nearby Pacific Ocean provides the needed humidity and moderate day temperatures and evening chilling to maintain fruit quality for the production months.

[0113]‘Yakima’ is distinguished from its paternal parent by the percent of marketable fruit. ‘Yakima’ percent marketable fruit is twenty percentile points greater than its paternal parent ‘Lili’ (U.S. Plant Patent No. PP25,849). Table 2 provides the field-testing data for fruit yield and fruit characteristics for ‘Yakima’ and its male parent ‘Lili’.
